                                PRINTRONIX, INC.

                            1994 STOCK INCENTIVE PLAN

                   PERFORMANCE SHARES PLAN PURCHASE AGREEMENT

      This Agreement is made as of April 9, 2004 between Printronix, Inc., a
Delaware corporation (hereinafter referred to as the "Company") and Claus Hinge
(hereinafter referred to as "Participant").

                                    RECITALS

      A. The Company desires to make an award of stock under the Company's 1994
Stock Incentive Plan to Participant to create an additional incentive for
Participant to further the interests of the Company and to reward Participant
for achievement of certain performance criteria.

      B. The Company recognizes that the criteria applicable to the vesting of
the awards may not be meaningful or reasonable in the event of a business
combination with one or more other entities after Participant has provided
services in an attempt to achieve the performance criteria.

      C. Accordingly, the Company desires to provide for early vesting in the
event of certain changes in control.

                                    AGREEMENT

      NOW, THEREFORE, the parties hereto agree as follows:

1. Purposes. This Agreement is entered into pursuant to and subject to the terms
of the Printronix, Inc. 1994 Stock Incentive Plan to provide Participant with an
additional incentive to serve the Company. Nothing contained in this Agreement,
however, shall be construed as obligating either Participant or the Company to
continue Participant's employment or other affiliation with the Company.

2. Future Sale of Shares. Subject to the terms and conditions set forth in this
Agreement, the Company hereby agrees to sell to Participant 20,000 shares of
Common Stock, $.01 par value, of the Company (hereinafter collectively
<PAGE>
referred to as the "Shares" or singularly as a "Share") at a purchase price of
$.01 per share upon the attainment of certain performance criteria specified
herein. The number of Shares shall be adjusted in the event any stock dividends,
stock splits, reclassifications, or other changes are declared or made in the
capital structure of the Company prior to actual issuance of the Shares.

3. No Rights Incident to Shares Until Issued. Participant shall have no rights
in the Shares including, but not limited to, the right to vote the Shares or
receive dividends thereon, unless and until the performance criteria have been
met and the Shares have actually been issued to Participant.

4. Performance Criteria. Except as provided in Paragraph 5 of this Agreement,
upon the concurrence of the following events if, and only if, they occur within
six (6) years of the date of this Agreement, Participant may purchase some or
all of the Shares as follows:

            (a) If, in any four (4) consecutive fiscal quarters the Company
      achieves cumulative profit before taxes ("PBT") of 8.0%, participant may
      purchase one-third of the Shares.

            (b) If, in any four (4) consecutive fiscal quarters the Company
      achieves cumulative PBT of 10.0%, participant may purchase two-thirds of
      the Shares.

            (c) If, in any four (4) consecutive fiscal quarters the Company
      achieves cumulative PBT of 12.5%, Participant may purchase all of the
      Shares.

5. Fundamental Change in the Company's Business. In the event the Company takes
action that will result in it no longer being publicly traded or in the event of
a change in control of the Company, then Participant may purchase all of the
Shares. "Change in control" as used in this Agreement shall mean the Company
enters into an agreement of merger or other acquisition in which the Company is
not the surviving entity.

6. Computation of PBT. Calculation of PBT shall be made in a manner consistent
with the Company's historical methods of financial reporting. Notwithstanding
the foregoing, PBT shall include any profit sharing contributions made to
employees of the Company and shall exclude expenses associated with the
<PAGE>
granting of restricted stock to any employees receiving restricted stock.

7. Nontransferability. No interest in or under this Agreement may be assigned or
transferred to any person whatsoever except that, after Shares have been issued
and to the extent there are no other restrictions thereon, the Shares may be
transferred.

8. Applicable Law. This Agreement shall be construed and governed by the laws of
the State of California.

9. Paragraph Headings. The paragraph headings are inserted for convenience and
ease of reference and are not to be considered in interpreting this Agreement.

    Executed at Irvine, California, as of the date first above written.
